How can I tell which directory the switch is currently using?

When you first boot the switch, the /flash/working directory is used; this allows you to save your initial configuration changes to the boot.cfg file. However, subsequent boots may result in your switch running from the /flash/certified directory. There- fore, verifying the current running directory is a key step any time you are configuring or monitoring the switch.

View the current directory by entering the show running- directory command. For example:

-> show running-directory

 

CONFIGURATION STATUS

 

Running CMM

: PRIMARY,

CMM Mode

: DUAL CMMs,

Current CMM Slot

: A,

Running configuration

: WORKING,

Certify/Restore Status

: CERTIFY NEEDED

tested, the contents of the /flash/working directory can be copied to the /flash/certified directory via the copy working certified command.

What happens when the switch boots?

During the boot process, the switch compares the contents of the /flash/working and /flash/certified directories. Based on this comparison, the switch determines which directory to use as its running software.

Working and Certified Are Identical

If the software in the /flash/working and /flash/certified directories are completely identical, the switch considers the software in both directories to be equally reliable. In this case, the switch will run from the /flash/working directory.

The switch runs from Working.

In this example, the switch is using the /flash/working direc- tory.

Can I save changes to the Certified directory?

Certified

Frelease.img Etc.

boot.cfg

Fbase.img

Frelease.img

Etc.

No. The /flash/certified directory is intended to store only tested, reliable configuration and image files. Configuration changes must be saved to the boot.cfg file in the /flash/working directory. Once those changes have been road-

When the switch is running from the /flash/working directory software, configuration changes can be saved via the

write memory command.
